ladsgroup@deployment-tin:~$ mwscript extensions/Wikibase/repo/maintenance/changePropertyDataType.php --wiki=wikidatawiki --property-id P31 --new-data-type "wikibase-item"
An error occured: New and old data type must have the same data value type.

@thiemowmde@Ladsgroup what is the list of properties that we want set for beta?
We should just totally override the defaults for beta so this doesnt happen.
Also, I dont even think the extension should have defaults in the first place, it should just be an empty array.
